Abstract Background The chemical process industry, mainly the production of organic and inorganic base chemicals, has a significantly high demand for electrical and thermal energy. This demand is constant in time and quantity due to mostly continuous production. On the contrary, the dependency of electricity supply in Germany on volatile wind and solar power increases. To use this power effectively, we propose the direct utilization of it in the chemical process industry. Methods To analyze the potential of the utilization of renewably generated power in the chemical process industry, the energy supply and demand has to be quantified. Therefore, methods are developed to calculate possible excess energies from the volatile renewable sources wind and sun. Furthermore, through a literature review, important production processes of the German chemical industry are characterized. Results The developed methods lead to time series of the future power generation by wind turbines and photovoltaic systems with a high temporal resolution. The overall gross energy consumption and the full load hours per year show a good consistency with numbers extracted from literature. Additionally, the specific energy consumption per ton product and the yearly production volume are chosen as process parameters to evaluate the potential. Conclusions A comparison between the calculated excess energy and the energy consumption for specific chemical products leads to the conclusion that the German chemical industry can function as energy sink for renewably generated power in the future. As a consequence, strategies have to be developed to make production processes more flexible in their operation.
